Podcasting might be the hottest new thing on the Internet.

A podcast is a talk or music radio show that's sent directly to an iPod or other digital music player through your computer. It's a new take on the growing technology called RSS that pushes text-based Web content to computers. But with podcasting, a listener subscribes to audio feeds. Think of it as Tivo for radio.

Podcasting derives its name from the popular iPod player. So far, it seems to be an outlet mostly for unpolished-sounding bloggers and pirate radio enthusiasts.

But mainstream broadcasters, like news station KOMO in Seattle and Boston public radio station WGBH, are beginning to offer podcasts, and observers see great commercial potential in podcasting.
